I c. l. AUTEN PREFABRICATED METAL DOORWAY original Filed May s, 1943INVENTORJ. Cmwzf 41/75/14 z Patented Aug. 29, 1944 UNITED STATES TENTOFFICE PREFABRIG'ATED METAL DOORWAY Claude I. Auten, Birmingham, Ala.,assignor to Tennessee Coal, Iron and Railroad Company, a corporation ofTennessee 3 Claims.

In a copending application, Serial No. 485,486, filed May 3, 1943, Ihave shown and described in detail a prefabricated house whose componentparts are made of cold formed sheet metal elements by modern massproduction methods. This application is a division of that copendingapplication.

One object of the present invention is to provide metal door frameelements adapted to be secured to the metal uprights of a prefabricatedhouse such as shown in the above identified application.

Another object is to provide overhead flashing and lower sill elementsspanning the space between the uprights at the door opening.

A further object is to construct and arrange the various component partshereinafter shown and described in detail so that they individually andjointly function in a manner hereinafter set forth.

An additional object is to provide an erected steel door frame to whichis hung a door by the simple operation of the insertion of hinge boltsin the loops provided in the two leaves of the hinge.

For a more complete understanding of the invention, reference should bemade to the following detailed description, the accompanying drawing,and the appended claims.

In the drawing:

Figure l is an end view of a prefabricated metal house with parts brokenaway to show parts of the improved door framing construction embodyingthe herein claimed invention.

Figure 2 is an enlarged vertical section on line 2-2 of Figure 1.

Figure 3 is an enlarged horizontal section on line 33 of Figure 1.

Referring particularly to the drawing, I6 represents a transverselyextending sill of substantially Z-shape in cross section supported on asuitable foundation or on corner posts. Secured to the top flanges ofthe sill I6 is a transversely extending sill angle 32 to the upstandingflange of which a plurality of wall supporting uprights 34 are secured.These wall uprights consist of sheet metal angles arranged back to backand having their lower extremities secured to the upright flanges of thesill angle 32. At their upper extremities the uprights 34 are secured toan eaves member 38. This member serves as-a lower support for inclinedroof rafter members forming no part of the present invention andtherefore not further referred to herein.

A plurality of sheet metal wall panels 40 having jambs !22 and themating portion l specific type of door frame structure adapted to beseated between spaced pairs of the uprights such as shown at 34-. In thebuilding illustrated, the spacing on centers between two adjacentuprights and therefore the widths of each wall panel is approximately 20inches. -Where door opening is to be provided, the lower portion of oneupright is cut away; thus the intervening space between adjacent walluprights at a door location is approximately 40 inches; It isunderstood, of course, that the dimensions given. are merely by way ofillustration and'may be varied to suit special circumstances. At theboundary edges of the particular pair of uprights 34 between which adoorway is to be installed, I secure substantially Z-shaped door jambs,as hereinafter more fully described in detail. Spanning the door jambsat the top of the doorway I provide a head stop and a head flashing,these parts being secured in a manner hereinafter pointed out morefully. And at the base of the doorway the upstanding flange of the sillangle 32 is cut and bent downwardly so as to form a tread surface or asmore fully hereinafter described in detail.

A typical doorway installation as illustrated is adapted to be made atany desired location. The door width is equal to that of two adjacentpanels, and the main framing elements thereof are adapted to be securedto the adjacent wall upright supporting members 3A. For example, asshown in Figure 3, at each side of each door location Z-shaped doorjambs I22 are provided. These are formed with channel-shaped extensionsI22 which overlap the adjacent flanges of upright members 34. The outerflanges [22 which are at right angles to the extensions I22, are adaptedto be fitted against upright battens 42 which overlap the outwardlyextended flanges of the uprights 34. The flanges I22 of the jambs aresecured by bolts I24 which penetrate the battens and the flanges of theuprights 34, as shown. Suitable hinges I26 are secured to one of the 26of the hinges screwed to the door I28.

Spanning the space between two adjacent uprights 34 at the top of thedoorway is an angleshaped head flashing I30 having an upright flangel3!) which is fitted against a head stop plate I32, this plating beinginterposed between the flange I3ll of the head flashing and a flange ofone of the uprights 34. At each doorway installation the sill angle 32will be out at parallel spaced points corresponding to the width of thedoorway; thus the horizontal portion 32 of the sill angle will form atread. The upright portion 32 will form a shoulder whose height is equalto the thickness of the plywood flooring 28. The portion 32 of the sillangle will be bent down flat over the top surface of the plywoodflooring, thus providing a protective tread at the door entry way.

While I have described in considerable detail the specific embodiment ofthe invention herein illustrated which reduction to practice on acommercial scale has shown to be highly desirable, it is not to beconstrued that I am limited thereto, since changes in arrangement andsubstitutions of equivalents may be made by those skilled in the artwithout departure from the'invention as I defined in the appendedclaims.

I claim:

1. Prefabricated metal house construction, comprising upright wallsupporting flanged members, sheet metal wall panels having flangessecured to said members, a pair of metal door jambs each bent toapproximately Z-shape each having an extended channel portion in a,plane parallel with said wall panels and clinched around a flange of arespective one of said members, another portion of each jamb at rightangles to said extended portion being secured to another flange of saidflanged member, a sill angle having an upstanding flange to which saidupright wall members are secured, a portion of said upstanding sillflange being bent downwardly alongside said jambs and spanning the spacebetween them to form a tread portion at the doorway defined by saidjambs.

2. Prefabricated metal house construction, comprising upright wallsupporting flanged members, sheet metal wall panels having flangessecured to said members, a pair of metal door jambs each bent toapproximately Z-shape with an extended channel portion in a planeparallel with said wall panels and clinched around a flange of arespective one of said flanged members, another portion of each jamb atright angles to said extended portion being secured to another flange ofsaid flanged member, a sill angle having an upstanding flange to whichsaid upright wall flanged members are secured, the upstanding flange ofsaid sill being cut adjacent each jamb and bent downwardly alongsidesaid jamb and spanning the space between them to form a tread portion atthe doorway defined by said jambs, and a head stop spanning the space atthe top of said jambs and secured to said wall supporting angle members.

3. Prefabricated metal house construction, comprising upright wallsupporting angle members, sheet metal wall panels having flanges securedto said members, a pair of metal door jambs each bent to approximatelyZ-shape with an extended channel portion in a plane parallel with saidwall panels and clinched around one flange of a respective one of saidangle members, another portion of each jamb at right angles to saidextended portion being secured to the other flange of said angle member,a sill angle having an upstanding flange to which said upright wallangle members are secured, the upstanding flange of said sill being bentdownwardly alongside said jambs and spanning the space between them toform a tread portion at the doorway defined by said jambs, and a headflashing of angular cross section spanning the space between andextending over the tops of said jambs and secured to said wallsupporting angle members.
